Can not open Turbo Macro Pro
Well we still got problem to open this program.
https://style64.org/release/turbo-macro-pro-sep06-style
I try to LOAD"$",8,1
But I got just shredded letters all over the screen on both D64-files.
How do you open up this program on Vice or C64?
Is it working flawless for you?
Thanks
Cheers |

when you load a directory you have to do ,8 as it makes a fake BASIC program. |

I do wonder what the design decision was for the directory listing to use the screen address as a load address. |

legacy from the PET drives? As the firmware system is similar isn't it?
0400 is the start of BASIC on a P.E.T |

exactly that, the PET always loads absolute, so the directory listing starts at $0401 |

You can't connect a 1541 to a PET, however, can you? =)
(It has a distinct "DIRECTORY" command next to LOAD, does that also stick to whatever is in the load address?)
But then BASIC programs start at a few different locations across computers compatible with the drive ($0801, $1001, $1c01), so picking any specific absolute load address would only work on one of them.
Loading to BASIC start goes over the entire program and re-links the BASIC lines by fixing up the linked-chain pointers, so yeah, i guess they just decided to stick to the original directory load address. |

Even worse : on the VIC 20 the start address of basic depends on adding/removing additional memory cards. |

No, but close: https://www.c64-wiki.com/wiki/SFD-1001
I think that has most of the code base the same.

There's a "CATALOG" command in BASIC 4.0, though there are PETs with 2.0 and 1.0 BASICs as well which I presume doesn't have that. |

even the 1541 is basically still a PET drive when it comes to the DOS :) |

Yes, but it was quite a hack when they reduced the multiple CPU implementation to one CPU, which they did for the 1540. |
